i ject'of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Pulling- @ver Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to pulling-over apparatus andits object is to provide a simple,

light and easily operated machine which may be mounted on either a bench or a floor base and is adapted for use on work where the requirements are not high for the operation of preparing shoes for lasting, as for example 1n /vclcltschoea or stitchdown workh as herein illustrated or for other cheap work.

One feature of this invention consists in a novel combination with toe and side grippers and a tread rest of an actuator which is operatively connected with the grippers in such a manner that its actuation will cause the toe gripper to seize the upper and then move forward longitudinally of the last before the side grippers seize the upper. Preferably the actuator is operated manually so that the upper may be stretched` longitudinally to the satisfaction of the operator before it is seized by the side grippers. Preferably the actuator that closes the toe gripper will move the tread rest away from the toe gripper.

Another feature of this invention consists in the combination with the side grippers and a sole rest', of connected operating mechanism organized to cause the grippers to pull the upper and to cause the rest to move the last backwardly within the upper while the side grippers arepulling the upper.

In its general organization as well as in various particular arrangements for performing its intended functions and in the mounted on a floor base; Fig. 2 is a front elevation of the same, also partly in secelevation partly in section of a simpler con-l struction arranged as a bench machine; Fig. 5 .1s a front view of the same in section, and Fig. G is a plan.

The base of the machine adjustably supports, or may be formed integral with, a column 2 through which is vertically movable an operating plunger 4. A horizontal guide member 5 is mounted in the vends of front and rear forks which rise from the column. The rear fork pivotally supports an upright arm G in which a binding screw 8 holds a lug 10 in vertical adjustment. A sole rest carrier l2 is pivoted to the upper end of the lug 10 as is also the sole rest plate' 14 the front end of which is upturned as at 15. The front end of the sole rest plate rests upon the upper' end of an adjusting screw 16 mounted in the sole rest carrier. The front end of the sole rest carrier is pivotally supported on the upper ends of levers 18 which are fulerumed at 19 to the guide member 5, the lower ends being connected by forwardly extending links 2O to thefront end of a horizontal bar 22 which extends longitudinally of the machine and is mounted in the head of the plunger 4. Depression of the plunger operates through the links 20 to rock the levers 18 as indicated by dotted lines, Fig. 1, to move' the sole rest rearwardly in the machine.

rlhe bar 22 has a collar 24 between upright ears of which is secured by a pin and slot connection a rod 25 to the upper end of which is pivoted the pulling lever 26 of the toe gripper, said lever having a rearwardly bent upper end which forms the upper jaw of the toe gripper. A spring 28 holds the toe gripper rocked toward the sole rest and against an adjustable stop 29 projecting from the sole rest carrier 12. The

spring 28 also holds the gripper in its ele-- the end of bar 22 and encircled below said 110 l and the sleeve 24 has been lexhausted afterk which the toe gripper will' be pulled downward ly. By this opei'ating mechanism there is effected first a seizing and then a foredrawing of the upper (inA ap roxmately thel slant of the top face of the ast, Fi r. 1, iinaccompanied by a downdrawing an finally a downdrawing is effected unaccompanied by further foredrawingf The length' of foredraw is not arbitrarily determined by the amount of lost motion between the parts 24 and 25 but is made variable, according to the resistance of the stock, by the spring 85.

The horizontal guide member 5 carries a side gripper carrying-sleeve 40 from opposite lateral sides of which, Fig. 2, extend arms to which are pivoted side gripper uides 42 said ruidos havin uiier and ower bearings in which can slide tubular gripper bars 44 upon the upper ends of which ai-e formed or attached the inner jaws of the side gripper-s. The outer jaws 45 are pivoted tothe inner jaws and are connected by links with side gri per operating rods 4G the lower ends of w ich are connected by links`with stems 48 that extend through the laterally projecting arms of a sleeve 5() carried by the plunger head bar 22. S rings 52 encircle the stems 48 between sai arms and the enlarged loweil ends of the stems and render yielding the movement transmitted to the side grippers from the plunger. rlhe said arms o the sleeve are extended'to form the handles 55 by which the operator may turn the sleeve 50 upon the bar 22 to depress one side gripper and raise the other for adjusting the up er transversely on the` last. Alternatively t e s ole rest may be mounted to turn about an axis extending lenethwise of the machine andcbe provided witi handles 57 corresponding to the handle's 55 and by which the last may be turned about a longitudinaly axis to adjust it within the upper. held by the side grip iers. Springs 56, which are shown as locate between the lower loearinnr for the gripper bar 44 and a collar fastened, grippers up in normal position pnd maintain them upraised' until the jaws have been closed.

A screw G0, Fin

`1, for adjusting the side griptpers longitudinally of the machine to- .war and from the toe gripper is confined on that bar hold theagainst endwise movement' in the guide tation of the screw slides the sleeves 40 and 50 and the two side grippers forwardly or backwardly. j

A screw 65, Fig. 2, is confined against longitudinal movement by ears on the sleeve 40 and has right and left threaded connections with the two side' gripper guides 42 for holding said guides in upright position and adjusting them together toward and from the sole rest, said guides turning during such adjustment about their vertical connect/ions with the arms of the carrier sleeve 40.

By the described connections the side grippers are closed and then drawn downwarc ly to stretch the ipper transversely.

There is a lost motion between the arms of the sleeve 50 and the stems v4% of the side gripper operating rodsmt'o permit vthe toe gripper to close and effect its foredrawing movement before the side grippers are closed. This is provided, see Fi 2, by 'a collar 51 the upward position o. which is limited b'y a pin extending through it and through the vertical slot in the stein 48. The space between the upper face of this collar and the lower face of the sleeve arms permits closing and pulling movementsS of the toe gripper before the side grippers seize it.

The operating connections from the plimger4 to the toe and sidev grippeils and the sole rest are preferably arranged to cordinate the movements of said vgrippers and sole rest sothat the toe gripper willfirst seize the toe portion of the upper loosely applied to a last the toe 'end of which is ubutted against the upturned end 15 of the sole rest.

After having seized the toe end of the up' per the toegripper will move forwardly to stretch the upper lengthwise without substantially bending it over the toe end of the last, following in this respect the method of pulling uppers described in United States iettersPatent No. 855,831 dated June 4, 1907`granted on application of Emery Bayard. During the forwardly drawing movement of the toe gripper the sole rest is moved rearwardly, carrying the last with it so that the upper is stretched lengthwise by the combined movements of the sole rest and ,the toe. gripper. 4Near the end of` the' forepany with the side grippers and preferably the sole rest continuing to move rearwardly until the end of the downdrawing movement.

The plunger may be locked or may be manually held with the parts in this position while the operator inspects the work and if necessary makes adjustments thereof by the use of the handles or 57. Then he fastens the upper to the last by tacks inserted through the upper intok the side faces of the end of the horizontal arm of a bell crank 64 which is fulcrumed upon the guide member 5. The pulling lever 62 has on its rear edge a shoulder which is held in engagement with the pivot rod 19 carried on the guiding member 5 by the action of the spring 65 on the bell crank. In this construction the leverage exerted by the bell crank and shoulder against the rod 19 maintains the toe gripper in normal relation to the sole rest until the gripper has seized the upper after which the pulling lever 62 swings outwardly from the sole rest. This toe gripper has only upper seizing and foredrawing movements.

ln the simpler form of the machine shown in Figs. 4, 5 and 6 the base which is formed to rest on a bench is made integral with the column and the plunger has on its head a forwardly extending arm to which is pivotally connected a downwardly and outwardly extending link 72 the lower end of which has a pin and slot connection with the toe pulling lever 75 which is fulcrumed to the base at 74 and is turned toward the sole rest by a spring lunger 76 as far as is permitted by the a justable stop 78 which is carried by the lever and adapted to engage a laterally fixed abutting face as shown in Fig. 4. n uppergripping lever having a jaw coperatmg with the jaw formed on the up# per pulling lever is pivoted to the pulling lever at 80 and has its rear end connecte by a spring 82 with the pin 73 there being also a pin and slot connection etween said rear end of the lever and the link 72. By this arrangement downward movement of the plunger 70 allows the spring 82 to move ing lever for closing the jaws land the grip i e upper while the slot in the rear seizing t end portion of the link 72 permits that link to move with relation to the pin 73 on the pulling lever. When the upper end of the slot is reached the link acts against the pin 73 to turn the pulling lever in the direction for moving-thetoe gripper away from the sole rest thereby pulling the upper forwardly substantially as described in connection with the forward movement of the gripper shown in Fig. 1.

The column is surrounded by a sleeve 85 which rests upon a spring 86 and has laterally extended forked ears between which are secured the lower portions ofthe pulling levers 88 of the side grippers, the upper ends of said levers being formed as gripping jaws. Thelevers 90, having cooperating jaws on the upper ends, are ivotcd to the. pulling levers and have their lower ends connected by links 92 to a cross bar 94 which is mounted in the plunger 70 by pin and slot connection which allows a portion of the movement for actuating the toe gripper to take place before the side grippers are closed. After the side grippers are closed they are moved downwardly together by force transmitted through the plunger' and the links 92 and grippers levers to the sleeve 85, the spring 86 yielding forthis purpose.

'The side grippers are pivotally connected to the sleeve 85 at 91 and may be fixed at different distances apart by the binding screws 93.

rlhe base of the machine pivotally supports a lever 95 which is heldby a spring plunger, Fig. 4, tipped toward the toe gripper and in the upper end of this lever the sole rest 14, having the upturned lip 15 as in Fig. l, is mounted for longitudinal adj ustment 'by a screw 96. The lever 95 has a roll standing against an inclined face on the sleeve 85 and said sleeve, when it is de- `pressed, rocks the lever 95 to move the sole rest and the last carried thereby rearwardly f in the machine.

ln the described machines the shoe is supported right side up and sole face downward and there is a downdrawing movement to stretch the upper, but the invention of course covers an equivalent updrawing movement in a machine in which the shoe is supported in reversed position.
